drain your vst tank and take a good look at the fuel.
i bet you have gunk inside your vst tank.

other than that i would bring it to a dealer.

could be anything.

I have a '93 Suzuki oil injected outboard. What should the top RPMs be for this motor. Presently it is on a 18.5 foot bay boat. The top RPM now is 4200. I just had all 4 carbs rebuilt and a new TPS installed. PLEASE HELP!

Check the fuel pressure to the injectors.
